(o1. ca -253) 10 Claims.

This invention relates to clothes wringers particularly of the power operated type, said invention being directed to mechanism in connection with the release and separation of the wringer rolls.

An object of the invention is to provide a novel means by which the Wringer rolls during wringing action will be more positively released when any usual hand releasemechanism is operated for that purpose.

More specifically the object of the invention is to furnish lmechanism whereby when any usual hand release mechanism is operated to separate the rolls the direct drive for the latter will be terminated to thereby more positively release the rolls and terminate their rotation.

Another object is to provide mechanism by means of which the gears in the usual gear box in the head of the wringer will be positively and automatically separated to thus instantly stop rotation of the wringer rolls when any usual release mechanism is operated to bring about the separation of said rolls.

Still another object is that while providing for the separation of the wringer driving gears the act of restoration of -driving relation thereof will be unhindered when the wringer parts are again brought into operative condition.

To the end that the invention may be fully understood the accompanying drawings are provided wherein- Figure 1 is a longitudinal sectional elevation of parts of a wringer structure, shown full size, wherein part of the invention is illustrated.

Figure 1a illustrates in perspective a portion of a two-part telescoping member entering into the present invention.

Figure 2 is a plan of some of the parts shown in Figure l, certain of them, together with other parts, being shown in section as produced on line 2-2 of said Figure 1.

Figure 3 is a transverse sectional elevation of parts shown in both Figures 1 and 2.

Figures 4, 5 and 6 are plans of parts shown in Figure 2 illustrating different positions thereof during operation.

Figure 7 illustrates in perspective one of the parts shown in the former figures.

Figure 8 is a side elevation of a structure shown in vertical section in Figure 1, and in horizontal section in Figure 2, and

Figure 9 is a side elevation of a notched shaft employed in the Wringer structure.

Figure 10 is a side elevation of the wringer in part section showing the general structure. r

In the figures, I denotes parts of the wringer frame or body which may be of a type conforming to any of the conventional forms thereof, while 2 is the usual driving pinion on a power driven shaft 3. That portion of I enclosing the pinion 2 and the shaft 3 may be termed the gear box. A short driven shaft 4 at right angles to the shaft 3 has its bearing .at 5 and 6 on the frame I. A collar 1 is secured -to the shaft 4 by a pin and has an opening in the end opposite to the shaft 4 for the reception of the stub end of the shaft 8. This operates as a universal joint type of drive for driving the shaft 8V of a lower wringer roll 9, said shaft having a bearing at IE),

for example, resting on the frame I. Fixed tov the shaft 4 but slidable therealong is a sleeve II carrying gears I2 and I3 to mesh with said pinion 2, comprising shiftable transmission gearing all more or less conventional. Midway of the sleeve II, in this instance, is an annular groove I4 and directly above said groove when the gears are in neutral is a boss I5 depending from the frame I forming a bearing for a shaft Iii operated by a lever Il, said shaft at. its end within the constituted gear box carrying eccentrically'` thereon a cam I8 having three flat faces I9, 2li, 2 I' at an angle to each other but also paralleling the axis of the said shaftl IE5. yDepending from the cam is a pin 22, also eccentric to the axis of the yshaft I6, said pin extending into and having suspended from it a member or slide 23 lying in the groove I4 of the named sleeve II and within which groove it is adapted to reciprocate, said pin freely turning in said slide.

Seated in what may be termed a pocket at 24- of the frame I is a two-part member 25-26, the lower of the parts being identified by 25, while 26 represents an upper one, see Figure la, and particularly Figure 8,` there being one of such two part members vat each end of the frame however.

to the structure, always tending to draw said parts together. The lower member is provided with a slot 2l which communicates with an'opening 28 for receiving a rock-shaft 29 paralleling Figure 8.

upon the same,'over a reduced portion 30. The

rotary adjustment of the shaft serves to so locate the portion 30 thereof that the said part .25"

is fixed relative to the wallgI as illustrated in the figure named, Whereasvk an adjustment of one- Interposed between thesetwo parts is a f spring 2S normally under compression and, due` half rotation of the shaft from the position shown permits the release of said part 25. Adjacent the reduced portion 33 is a pin Sti' which upon rotation of said shaft serves to engage an abutment 362 by which the entire member 25, 2S is lifted during which time the slot 2'! permits said reduced portion 33 to pass through it.

It is to be understood, that other means than that shown for securing the part relative to the frame may be employed for the purpose of the present invention to be understood presently, the means illustrated being but one form suitable for the purpose.

A part of a closure member for the top of the wringer is shown at 3|, this having at veach end a lug 32 whose upper surface is preferably slightly downwardly slanted, one of which is shown in Figure l, the part 26 of the said two part member 25, 26 having a hook-portion 33 adapted to engage upon said lug, a portion of any usual hand wringer-release mechanism old and well known serving to maintain the hook portion 33 in position engagement with said lug. In. this instance a rod 34 abuts the portion having said hook portion 33 to hold the hook on said lug 32 and which by means not necessary to show herein, serves to permit said rod to be removed from said hook portion to permit the lug 32 and top cover 3| to rise. In Figure l0, the top cover 3| is shown held down by engagement of the hook portion 33 over the lug 32. In Figure 1, the top cover 3| is shown in the same position, the position of the hook portion 33 on the lug 32 being shown. in dotted lines. The full line position of the hook portion 33 shows the hook portion in the `retracted position and at the moment the top cover 3| is free to rise and the hook portion 33 is free to be drawn downward by the action of the springs 26.

An upper wringer roll B', in this instance only, is shown suspended from the closure member by means of a hanger-bearing 2,.though the roll may be otherwise controlled..

Upwardly extending from the lower part 25 of the said two part member, Figure 1, is a portion 25 provided with an angular surface 252 facing in the direction of the gearing previously described. Lying adjacent said surface is one end of a rod whose other end, Figure v2, is slidably guided in a tubular extension 3G' projecting from a boss 3'! forming in this instance a part of a cover-plate 38 for the gear box, the bore of the extension 38 communicating with a bore 39 of said boss 3.1, the axis of which is in line with that of the described shaft |3 while lying at right angles thereto. This rod 35 functions as a communicating element between the operating gearing and the mechanism including the parts 25, 26 which are released when the top closure is released and is permitted to rise. The detailed construction and operation `of these parts will be further described.

A Vmember including a piston-like part 3, which may be designatedl a key member, adapted for reciprocation is slidable in said bore 39 and provided with a head 4| to abut the cam I3 as best illustrated in Figure 3, being adapted to bear against any one of the faces 9, '20,.and 2| thereof, there being an expanding spring 39' in said bore 39 constantly urging the member 4G toward said cam. Preferably a ball 35 lies in the bore of the extension 36 to abut the member itil and is also adapted to enter a notch 4D. of said member adjacent. said head 4|... The ball serves as a'freely revoluble end piece for the rod 35. The

rod 35 is constructed of such a length as to be held under compression between the member 4i, ball 35', and the said two-part member 25-26 when the two-part member is in its normal operable position.

It may here be stated that as shown in Figure 2 when the gears l2 and |3 lie in the neutral position the forward flat face of the head abuts the widest face 26 of the said cam I8 at which time the member 40 lies in such position within the boss 3l' that the ball 35 lies against its side. However, when the cam is made to lie in either of the positions shown in Figures 5 and 6 due to swinging the hand lever Il to engage one or the other of the gears with the pinion 2, the movement of said cam forces the head 4| and its member il compressing the spring 3S whereupon the ball 35 lies in the recess 4B as illustrated in the gures last named, it being understood from the drawings, Figure 3, that the cam since eccentrically mounted on the shaft I6 serves to shift the sleeve in either direction due to the connection of the cam with the slide 23 through the pin 22.

Attention is drawn to the fact that whereas the line of thrust of the piston-like member 4B and its head 4| is directly in line with the axis of the shaft 6 and the pin 22 of' the cam in Fig res 2 and 4 in the neutral position of the gears, said line of thrust in Figures 5 and 6 is transferred to either side of said line of thrust or at a corner of the said headt' and passing through the said pin only, no action of the part due to the spring 39' resulting, however, since the ball 35' lies in the recess 40.

In the construction described, or its equivalent, for securing the part 25 of the two part member with respect to the frame I the upper portion 26 by means of the hookportion 33 and the lug 32 of the closure member 3| holds and' tends to draw the latter elastically downward through the springs 26', any such meansl as a releasable rod 34described providing for maintaining posi-` tive engagement of said hook-portion and lug as previously stated.

Figure 1 shows the gears l2, i3, in the neutral position, neither being in engager-nent with the driving pinion. Atr this stage, the rod 34 is retracted from the hook member 33 and the top cover 3| is free to riseand the catch 33 is free to be drawn down by the inuence of the springs 2E. The position of the parts 23 and 33, as

shown in full lines, indicates that the gears |2` and I3 are in the neutral position.

Let it be supposed, new, that one or the other of the gears i2, i3 is in mesh with the pinion 2 while the wringer is in operation, doing work, the named cam I8 at this time having shifted thehead ti .to either position shown in Figures 5 and` '6 where'it is held by the ball 35. When the parts 25 and 33 are in the `dotted line position, as shown in Figure l, the machine is in the operating `position to do work. At this time the rod 35 holds the said ball in the position named due to abutting the inclined face 252 of the portion 25 while the part 26 has looked engagement with the lug 32 of the closure member 3| the part 25 thus'being xed so that the spring 39 at the gear box cannot act to eiect the said rod 35.

When necessary to `release the rolls by striking any usual release mechanism (not shown in its entirety) on the closure member` the rod 3,4 thereof is drawn away from theportion carrying the hook-portion 33,

the latter being now free to slip off the lug 32. Due to the strain of the springs 26 the part 26 carrying said hook portion is pulled downward thus positively drawing the hook portion down over the lug said portion thus causing the two partrmember 25, 2S to tilt laterally away from the rod 35 the part 25 thus freeing the rod 35 and ball 35' permitting the spring 39 to operate the head 4I within the gear box. The ball 35' is pushed out of the notch. et'. During the tilting of the member 25,'26, it moves from the dotted line position (Figure l) to the full line position shown in the same ligure and in Figure 2. The head 4| thereupon operates upon the cam I8 and carrying it to the position shown in Figure 2, the gears l2, i3 thus being carried to the neutral position or entirely free of the driving pinion 2 by the action of said spring 39'. Thus while the wringer rolls have been separated by releasing the closure member carrying the upper roll, the rotation of the power driven roll has also been terminated.

Further in regard to the manner of engagement of the hook portion 33 with the lug 32, it may be noted that the engagement between those parts is unstable, the former being prevented from slipping off from the latter by the thrusting action of the arms 34 when the closure is in the operative position and the rolls are under compression. The relative positions of the hook portion 33 and the lug 32 at the moment of disengagement are represented in dotted lines. The tilted position of the members 25 and 26 is also shown in dotted lines and it will be apparent that these parts are permitted to move more at their upper portion than at the bottom, as will be clear from the dotted line position.

In restoring the parts to operating position the rock shaft 29 is rotated to raise the two part member 25, 25 se that the hook portion 33 may be reengaged with the lug 32 of the closure member whereupon a rotation of the rock-shaft will permit the part 25 to lower, the corner of the reduced portion 33 of said shaft engaging the said part 25 at the slot 2'! drawing the part down to the position shown in Figure 8, while the hookportion of the part 25, however, remains in engagement with said lug 32. This action restores the portion 25 to position and bears against the rod 35 to carry the ball 35' toward the bore 35,

the ball lying against the member 40 and free to enter the notch 4U to lock the head in either position shown in Figures and 6 with the gearing in mesh.

While the rod 35 has been described as having a bearing at one end upon the part having the angular surface 252, it is to be understood that said rod may bear against any other part corresponding in result to that produced by said part 252.

A form of mechanism has been illustrated and described herein which serves to bring about the neutral relation of the gears that drive the rolls when operating the wringer-roll. release mechanism, but it is understood that it is not the desire or intent to be conned thereto since other means may perhaps be employed to serve in a like capacity. And, of course, any desired type of wringer roll release mechanism may be employed to accomplish the end sought. In some of the claims the ball and the rod 35 will be referred to by the term means in the interest of brevity.
